A-4 WebPak 3000 DC Drive Hardware Reference
Drive Input/Output Specifications
The following sections describe drive inputs and outputs. Refer to section 2 for terminal strip
connections and wiring diagrams.
Logic Inputs
ATTENTION: Connecting an external power source to any of the +24 volt
connections (terminals 1, 7, 11, and 14) on the regulator board terminal strip will
damage the drive. DO NOT connect the external power source to the +24 volt
connections on the regulator board terminal strip. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.
The logic input circuits can be powered either from the internal +24 V DC power supply or from
an external +24 V DC power source. The internal +24 V DC power supply is available at the
regulator board terminal strip (see Figure 2.8b). If an external power source is used, only its
COMMON must be connected to 24V COM on the regulator board (terminal 15). 24V COM is
internally not grounded, but may be externally grounded if required by the users control wiring.
Electrical Specifications:
Input Voltage ...................................................................................................... +24 V DC
Turn On Voltage .......................................................................................................... 8 V
Turn Off Current ..................................................................................................... 0.5 mA
Common............................................................ All input circuits have the same common.
Logic Outputs:
The logic output circuits are normally open (when de-energized) relay contacts. When
energized (contacts closed), the three circuits indicate the following drive conditions:
Running 27 to 28, Alarm 29 to 30, No Fault 31 to 32
Electrical Specifications:
Operating Voltage ................................................................ 250 V AC maximum
30 V DC maximum
Switching Current ............................................................ 2 A maximum resistive
1 A maximum inductive
Analog Inputs:
The three customer analog inputs are
• Manual Mode Reference
• Automatic Mode Reference
• DC Tachometer Feedback.
These inputs are converted at 12 bits plus sign at their full range. The electrical specifications
for each of these is listed below.
Electrical Specifications:
